universally mounted dirigible lamp, having mechanism for operating thesame, in-

eluding novel gear elements which facilitate smooth and eflicientmanipulation of the spotlight.

Another object of the invention is to provide operating mechanism forthe spotlight, wherein electric conductors are utilized which arecarried by the movable parts of the operating mechanism and so arrangedas to prevent any possibility of the same being broken or twisted, andwhich are so disposed as to permit ready assembling and disassembling ofthe spotlight when desired, 'ithout the necessity of fishing wiresthrough the parts of the operating mechanism.

Still another object of the invention is to provide a spotlight of acharacter adapted to extend through the windshield structure of a closedtype of automobile, and wherein supporting means for the spotlight areutilized which may be readily adapted to supporting posts of varioussizes and contours, and wl ich includes a ball and socket ar-- rangementpermitting ap lication of the spotlight structure at di erent angles tothe supporting post, together with a bracket of bendable material whichmay be bent to form so as to be secured to the supporting post in anydesired position.

Other and further objects of the invention will more clearly appear fromthe description and claims hereinafter following. In the drawingsforming part of this specification, Figure 1 is a side elevational viewof the spotlight, the front and rear portions of which, and thesupporting post to which tne spotlight is connected, being shown invertical longitudinal section, and the lamp head being partly brokenaway to expose the interior thereof. Figure 2 illustrates respectively aperspective view of an operating gear associated with an operating shaftof the spotlight and a perspective view of the cooperating gearassociated with the lamp head of the spotlight. Figure 3 is a transversevertical sectional view through the forward portion of the lamp,corresponding substantially to the line 3-3 of Figure 1. Figure 4 is atransverse vertical sectional view through the rear portion of theoperating mechanism, corresponding substantially to the line 44 ofFigure 1. Figure 5 isa horizontal sectional View through the rear end ofthe lamp, corresponding substantially to the line 55 of Figure 1.

Figure 6 is an'e-nlarged fragmentary, vertical sectional view of thespotlight, showing the supporting means therefor. Figure 7 is anenlargedfragmentary horizontal detailed sectional view through the lamp headgear and showing the same in mesh with the related gear of the drivingshaft. Figure 8 is an enlarged fragmentary vertical sectional viewthrough the lamp head gear and showing the same in engagement with therelated ear upon the drivingshaftJ As shown in the drawings, thespotlight is adapted to be applied to the corner .post of the windshieldstructure of a closed, car, said corner post being indicated in thedrawings by the reference character 6. In order to mount the spotlightit is necessary to pro vide an aperture extending transversely throughthe post 6 at any suitable angle desired, an aperture 7 being indicatedin the drawings. To the outer face of the post 6, in proper positionwith reference to the aperture 7, is secured a supporting bracket 8. Thebracket 8 is preferably elongated in form and has its outer marginaledges strengthened by means of a pressed corrugation 9, inwardly ofwhich are provided a number of openings in the bracket to permit thepassage of holding screws 10, which are utilized to secure the bracketto the post 6. Centrally of the bracket 8 is provided an outwardlyextending truncated ball-shaped member 11, having a central opening 1:2.Co-operating with the bracket 8 is the lampcarrying member 13, which isin the form of a tubular member, having a flared portion 14, the innersurface of which is globular to co-operate with the ball-shaped portion11 of the bracket, there being provided vithin the flared portion'anannular flange 15, which provides a shoulder to co-operate with a partpresently referred to. The member 13 is provided with a hollow tubularextension 16, which extends rearwardly through the opening 7 in the post6 a suitable distance, and forms with the lamp-carrying member 13 anouter shaft adapted to rotate about its longitudinal axis upon theball-shaped member 11. A threaded annular portion 160 is formed upon theextension 16 adjacent the ball-shaped member 11, and threaded upon theportion 160 is a ballshaped part 161, which fits the inner surface ofthe ball-shaped member 11, the member 161 being provided with an annulargroove 162 which may be filled with a felt washer,v

which bears upon the inner surface of the ball-shaped member 11. j Theextension 16 is provided at the rear of the post 6 with a holdingbracket 17, said bracket having bendable prongs 1818 adapted to besecured to the post 6 by means of screws 19. The bracket 17 is providedwith a sleevelike portion 20, which is split to provide a pair of ears,indicated at 21, which fit about the extension 16 and are securedtogether by means of a bolt 22, which may be tightened or. loosened asdesired, to thereby vary the frictional contact of the sleevelikeportion upon extension 16. The sleevelike portion 20 is provided with anarcuate extension 23, adapted to co-operate with lugs 24 at oppositesides of the collar 25. The collar 25 is clamped to the extension 16 bymeans of a bolt 26, the lugs 24 being adapted to co-operate with thearcuate portion 23 to limit the turning movement of the extension 16,and further to hold the extension 16 against forward longitudinalmovement.

The lamp-carrying member 13 and the extension 16 are rigidly securedtogether by a driving fit as indicated at 29, and the two form the outershaft which is provided with a central bore 27, in which is rotatablymounted a shaft 28. The forward end of the shaft 28 is provided with agear made up in the form of an annular enlargement 30, which fits in acounter-bored socket 31 of the lamp-carrying member 13, a coiled spring32 being interposed between the member 30 and the shoulder 33, providedby the bottom of the socket 31. The annular member 30 is provided withan annular series of teeth along its forward edge, indicated 1 by thereference character 34. The teeth 34 are of peculiar formation, beingdefined by a series of cut-out portions 35, the opposite de fining walls340 of which are straight and disposed parallel to each other, andparallel to radial lines projected from the longitudinal axis of theshaft 28. The bottom of each cut-out portion is curved, as indicated at36. The teeth 34, so defined by the cut-out portions, have theiropposite sides undercut, as best shown in Figures 2 and 3, and saidteeth are of a character to co-operate with a gear connected to the lamphead, as hereinafter described. Disposed within the base portions of theteeth 34 at the end of the shaft 28 is a central annular portion 37,which projects beyond the forward edges of the teeth 34 to form a thrustbearing.

Co-operating with the gear 30 is a gear 38, which rotates about an axisdisposed at right angles tothe axis of rotation of the shaft 28. Thegear 38 comprises a journal portion 39, provided at its lower edge withan annular flange 40 against which the central projection 37 on the gear30 bears, and outwardly of the flange 40 of the gear 38 is provided withgear teeth 41, adapted to mesh with the gear teeth 34 of the gear member30. As best shown in Figures 2, 7 and 8, the teeth 41 of the gear 38 areof peculiar formation so as to co-operate with the teeth 34 in apeculiar and eflicient manner, whereby great ease and smoothness ofoperation are obtained. The teeth 41 are each formed as a segment of aball at its engaging surface. The curved surfaces 410 are adapted to bepresented for engagement with the flat walls 340 of the gear 30 duringthe horizontal approach and recession of said surfaces longitudinallywith reference to the shaft 28, as best shown in Figure 7, while thecurved surfaces 411 are simultaneously presented to the gear teeth 34 totake care of the movement of the teeth 34 in their vertical plane ofmovement, as shown in Figure 8. In other words, the teeth 34 and 41travel relatively to each other in two planes and the curved surfaces410 of the teeth 41 provide a rolling engagement between the teeth 34and 41 in a horizontal plane, while the surfaces 411 provide a similarrolling engagement in a vertical plane, the surfaces 410 and 411 mergingto provide a ball effect so that the ball surfaces roll upon the fiatwalls 340 in two directions, producing great smoothness of 1 operationand efficiency in action. For this way tight running gears are providedwithout lost motion between the teeth thereof, the flange 40 bearingupon the annular projecting portion 37 in such manner as to maintain apredetermined clearance for the teeth and eliminate bottoming of theteeth, which ordinarily results in the teeth bumping over each otherduring rotation of the gears. The journal portion 39 of the gear 38 isrotatably mounted in a nut 42 threaded into the chamber 43 of thelamp-carrying element 13, which nut is provided with an annular channel44, in which is mounted a coiled spring 45 which bears downwardly uponan annular shoulder 46, formed upon the gear 38. The journal portion 39of the gear 38 is provided with a reduced annular portion 47 over whichfits a washer 48. The lamp head is provided with a portion 49 whichrests upon the washer 48, and the reduced portion 47 of the gearprojects through the portion 49 of the base of the lamp. The portion 37is still further re duced and threaded for the reception of a nut 50threaded thereon, between which and the adjacent surface of the portion49 of the lamp is interposed a washer 51, the arrangement being suchthat the lamp head is maintained in position and rotates with thejournal portion 39 of the gear 38.

The outer shaft provided by the extension 16 and lamp-carrying member13, at its rear end, carries a handle support 52, which is in the formof a casting having split sleevelike member 53 at its forward end, whichfits over the end of the extension 16 and is rigidly detachably clampedthereon by means of a bolt 54. The handle support 52 is provided with anannular flange 55, in which is rotatably mounted the journal portion 56of a gear 57. The journal portion is provided with a flange 58, whichbears against the flange of the support. The handle proper, indicated at59 rests against the undersurface of the flange 58, and the handle 59 isprovided with a' central hollow sleeve 60, extending therethrough,adapted for the reception of a screw bolt 61 which is threaded into thegear 57. The gear 57 is provided with an extension 62, having a reducedportion 63 extending through the wall 64 of the handle support, whichreduced portion is internally threaded for the reception of a set screw65, the head of which bears upon a flanged friction-generating element66, the latter being provided with a sleeve portion which rests againstthe shoulder provided by the extension 62. By this arrangement too freerotation of the gear 57 is prevented. The handle support is providedwith a socket 68, in which is mounted the journal portion 69 of a gear70, which meshes with the gear 57, the gear 70 having a centralpolygonal opening adapted for the reception of the end 71 of the shaft28, which is polygonal in section to fit the opening in the gear 7 0,whereby the gear 70 and shaft 28 rotate in unison.

The electrical connections include a conductor 72, extending from asuitable source of supply to a switch block 73 of any suitablecharacter. The switch block 73 is preferably supported by a cup-shapedmember 74, detachably connected to the rear end of the handle support 52by means of set screws 75. The switch 73 is adapted to be operated bymeans of a lever 76, which projects through the rear wall of thecup-shaped I member 74. Connected to the switch block is a resilientconducting member 77, which extends forwardly past the extension 66 ofthe gear 57 and is coiled about the same, as indicated at 78, andprovided with a reverse lly turned end portion 79, which resilientlybears upon the rear end of a conducting rod 80. The conducting rod isrigidly mounted in the shaft 28 so as to rotate therewith, and extendsentirely through said shaft to a position where it projects from theforward end thereof, as indicated at 81, the portion81 being annularinform. Co-operating with the portion 81 of the conductor 80 is aconductor 82, carried by the journal portion 39 of the gear 38.Conductor portion 82 is provided with a plunger section 83, slidably.disposed within a flange member84 driven into the lower end of a thimble85, fitting within a block of insulating material 86, disposed in thecentral chamber 87 of the journal portion 39 of the gear. The plungersection 83 of the conductor is provided with a flange 88, adapted tolimit downward movement of the conductor 82, and interposed between theupper surface of the flange portion 88 andthe bottom of the thimble is acoiled spring 90. The thimble 85 is connected to a wire 91 which extendsupwardly through the annular portion 47 of the gear 38 and the threadedportion thereof and the nut 50, to the base of the lamp bulb, indicatedat 92, thereby conipleting one pole of the circuit, the remaining polebeing suitably grounded upon the lamp structure, and the circuitcompleted to the battery of the car by means of the wire 93. Inoperation, when it is desired to swing the outer shaft, composed of theextension 16 and lamp-carrying member 13, about its axis so as to impartswinging movement to the lamp head, the handle 59, is grasped by thehand of the operator and oscillated to and fro, without rotation aboutits individual axis. The movement of the outer shaft is limited byreason of the stop lugs coming into engagement with the portion 23 uponthe bracket 17. Too free rotation of the extension 16 is regulated bythe clamping ears 21 on the sleeve-like portion of the bracket 17.

l/Vhen it is desired to rotate the lamp head about its vertical axis,the handle 59 is rotated about its individual axis, imparting rotationto the gear 57, the gear 70, the shaft 28, the gear 30, the gear 38, andthence through said gear to the lamp head. Of course, it will beappreciated that rotation, both about the horizontal and vertical axes,may be effected simultaneously, if desired, by one hand of the operator,through combined swinging movement of the outer shaft and rotation ofthe handle on its individual axis, which effects rotation of the shaft28. The supply of electricity to the lamp is controlled through theswitch lever 76, which may be manipulated through the fingers of thesame hand of the operator which is utilized to impart the requiredmovements to the lamp head. The electric circuit is effected by reasonof the fact that the resilient conductor 77 continuously bears upon therear end of the conductor 80, which in turn rotates with the shaft 28and bears against the conductor 82 which, through the thimble 85 andwire 91, conduct the current to the base of the lamp bulb, the otherpole of the circuit being grounded on the lamp struc-' ture.

The lamp-carrying member 13 and extension 16 may be disposed of anydesired angle with reference to the post 6, by reason of the universalconnection of the flared portion 14 of the lamp-carrying member with theballshaped element 11, as will be understood, the bendable prongs 18 ofthe bracket 17 being bent to whatever position is necessary, wherebythey may be secured in proper relation with respect to the opposite sideof the post 6. In any position in which the outer shaft, comprising thelamp-carrying member 13 and extension 16, may be mounted, it is affordedfree rotation upon the ball-shaped member 11.

The lamp, as thus provided, may be conveniently assembled anddisassembled during application, or for purposes of repair, and assumingthat it is desired to disassemble the lamp from its position as shown inFigure 1 it is only necessary to loosen the bolt 54, remove the handlesupport 52, and the collar 25, after which the forward portion of thelamp, including the lamp-carrying member and extension 16, may be movedforwardly and completely removed from the mounting, it being noted thatthe gear slips off of the polygonal end 71 of the shaft 28 during thismovement. The reverse operation, of course, takesplace when the lamp isbeing applied to position. It is particularly pointed outthat theelectrical connections are susceptible of disassembly with the partsabove referred to, without the necessity for fishing wires through theshafts, or other awkward procedure. Access is provided to the switchthrough removal of the cap-shaped member 74, carrying with it theresilient conductor 77. Due to the provision of the particular type ofgears provided between the lamp head and the forward end of the shaft28, the gears are held in tight engagement so that no lost motionoccurs, and the teeth thereof mesh in such manner that the same do notbump over each other. Particular attention is also called to the factthat the conductor rotates with the shaft 28, while the conductor 82 iscarried by the journal for the lamp head in resilient contact therewith,whereby any amount of rotation of the lamp head, with respect to thelamp-carrying member 13, will have no effect in interfering with; theoperation of the conducting means and does away with any possibility ofkinking or breaking of wires, so common in othertypes of lamps.
